下面就让小编来为大家介绍几道ACT考试数学练习题的相关内容吧，大家要好好把握，希望能够给准备ACT考试的同学带来帮助。
Question #1: What is sec(a)sin(a) + csc(a)cos(a) , if a = 45o?
(a) √2
(b) 2
(c) 1
(d) 1/√2
(e) 1/2
Answer: sec(a)sin(a) + csc(a)cos(a) = [1/cos(a)]sin(a) + [1/sin(a)]cos(a) = sin(a)/cos(a) + cos(a)/sin(a) = (√2/2)/(√2/2) + (√2/2)/(√2/2) = 1 + 1 = 2.
Question #2: In the standard (x,y) coordinate plane, 3 corners of a square are (4,–3), (–4,3), and (–4,-3). What are the coordinates of the square’s fourth corner?
(a) (1/4, -1/3)
(b) (4, 3)
(c) (3, 4)
(d) (3, -4)
(e) (3, -4)
Answer:
The easiest way to solve this problem is to sketch the 3 corners of the square. We notice that the fourth corner of the square is (4, 3).
Question #3: Prizes totaling $60,000 were awarded unequally between 3 contestants. Which of the following choices could be the highest prize?
(a) $5,000
(b) $10,000
(c) $15,000
(d) $25,000
(e) $65,000
Answer: The highest prize should be higher than one third of $60,000 and lower than $60,000. The only answer that satisfies this condition is $25,000.
